Hi Keith, how have you been? Still taking good care of the 67 L89 Vette roadster you bought from me?
My take on the B/J auction is that the big money was spent on custom and made-up clone cars. The real cars like yours and mine went down in value.

For example the COPO Chevelle that sold for $60K. So save yourself the insurance renewal money and unload your cars cheap to me.
I'm just kidding you of course. Just don't know how to equate B/J auction sales to actual values. Most didn't seem to have any rhyme or reason.
